l to sale of `tickets or commodities, admissions, etc., which have beenmade at the different selling points. l

It frequently. occurs, for example, at public gathering places thattickets, an indication of the total of values of which is desired, aresold during simultaneous periods, with respect tothe different featuresof the exhibition and at a large number of widely distributed pointsand, further, that these tickets withv respect to each'ieature are soldin a number of`difierent values. Furthler the sales are frequently madeby means of rapidly operating ticket vending machines at ratesdetermined largely by the capacity ofthe machine itse f. a

One of the objects of our inventionvis to provide an electric systemwhereby the total value 'represented by all tickets sold and the. totalvalue represented by tickets sold with respect g to each of the diierentfeatures may be continuously indicated during the period in which salesare made. A further purpose of the invention is to provide such a systemwhich is capable of operating with sufficient rapidity to indicate theabove 30 .mentioned totals substantially simultaneously with the sales,that is, such that the totalswhich are indicated follow the progress ofthe sales with substantial accuracy, or with the degr'e of accuracy thatis required, as by renderingthe indi- 5 cation in even hundreds orthousands. A furthe;` object of our inventionis to provide a systemcapable of accomplish-ingv the above result notwithstanding the rapidoperationyof the ticket vending machines.-

40- Another purpose of the invention is to provide means whereby .thedesired totals may be ,indicated by any suitable means as by means oidials with cooperating pointers, or by means of a lamp, or by means ofgroups of lamps which are respectively controlled so that they arelighted so as to form the'digits of the quantity to be -indicated In theoperation of the system tobe described,

as briefly stated, an electric impulse is produced 50 in response toeach operation of .the different ticket vending machines. Each impulsetherefore represents a vdefinite value which is to be included in thetotal. Means-are provided'where-' by all of the impulses from each grouppista- 55 tions which transmit impulses representing equal meansincluded in (Cl. 23S-92).

value are collected, without confusion of impulses, f

upon a single conductor and caused to actuate the totalizing equipmentwhereby all impulses produced by all of the ticket vending vmachines arereduced to impulses of equal value. These impulses of equal value arethen automatically added toA produce an indication of the desired totalin even hundreds, thousands, etc. as is desired.

' It will thus be apparent that, while we particularly mention the useof our invention-in connection withthe totallzing of the value oftickets sold at public places, exhibitions, theaters and the like, it isby no means maybe employed wherever may be produced in response valuewhich is to b included in the total to be indicated. For example, ourinvention has utility in connection with the totalizing of the readingsof integrating power meters. Each of the meters, the reading of which isto be included in the total, may be provided vwith means whereby animpulse is produced in response to each unit of power integrated by therespective meters. The Jimpulse transmittedin response to operationmeters may represent different units of power as desired and the metersmay be variously loan electric impulse cated. All of these impulses willthen be causedl to each unit of of different' limited thereto andy to'abtuate the totalizing equipment to be described whereby the totalpower integrated by all of the meters may be indicated.

Thus many other'applications of our invention will readily suggestthemselves to one skilled in the art and all of such applications arecontemplated as` within the scope of the present invention.

The novel features which we believe to be characteristic of ourinvention are set forth with particularity in the appended claims. Ourinvention itself, however, both as to its organization and method ofoperation, together with iurther objects and advantages thereof, maybest be understood by reference to the 'following description taken inconnection with the accomv stations, which in order to simplify thedisclosure with each group ls an additional selector switch.

are shown as pairs of contacts, which may be controlled manually or bymeans of a device the operation of which represents the values which areto be included in the total to be indicated. Ac-

cording to the arrangement shown these contacts' are momentarilyinterrupted in response to each operation of the ticket vending machine,for example, or they may be momentarily interrupted at a rate determinedby the rate of operation of a power integrating meter, or by any othersuitable device not shown. Thus momentary interrup-f' tion of any pairof contacts represents a certain value which is to be included in thetotal. These contacts are arranged in groups in accordance with thevalues represented by the operation thereof. Thus, for example, assumingthat the operation of contacts I or'2 represents a value of 2. Thesecontacts and all other contacts, the operation of which represents thisvalue, will then be included in a single group designated on thedrawings as group 1. Similarly assuming that the operation of each oi'contacts 3 or 4 represents a value of 5 thenthese contacts and allcontacts, the operation of which represents this value, will be includedin another group desig-- nated on the drawings as group 2. Similarly theoperation of contact 5 may be assumed to repre- Sent a value o f 10, andthe operation of contact 6 a value of 50. For reasons which will laterbe indicated we have included these contacts in a single groupdesignated on the drawings as group 3.

It will be apparent` as the description proceeds that operation of thedifferent contacts may represent any desired value, the circuitadjustments necessary in any case being obvious toone skilled in theart. For the purpose of illustrating the operation of the system withoutunneces-4 sary complication of the drawings, and not in any way..tolimit the protection herein claimed, the above values are assumed, butthree groups are indicated, and further, only two contacts in eachVgroup are illustrated.

It will be noted that each contact I, 2, 3, etc.

lhas associated therewitharelay I', 2', 3', etc.

is controlled by any of the relays associated withA contacts in itsrespective group. Also associated A', B' which functions as a countingor adding device. Each of these selector switches consists of aplurality of semi-circular banks of contacts each of which has acooperating Ywiper associated therewith. These wipers are connected toa` common shaft and are adapted to be moved in a step by step mannerover the contacts in their respective banks inv response to theenergization and deenergization of a suitable driving motor magnet whichis associated therewith. While the number of contacts in each bank maybe any desired number, usually they are constructed in practice vwith 25contacts in Y each bank.

ASwitches of this type are well known in the lart and oneconstructionwhich may be employed is fully disclosed in Letters Patent1,472,465 to 0,'11.` Forsberg, granted October 30, I1923. While we haveshown selectors of the'well-known rotary type, itl will be obvious tothose skilled inthe art be used. 'I'he arrangement shown in the drawingsis suchthat upon operation of any contact or combination of contacts inany group causing the operation of the associated relay I', 2', 3', 4'the respective collecting switch A, B rotates over its entire bank ofcontacts and transmits an Impulse to the adding switch A', B', of therespec-r. tive groups corresponding to each of the contactsV i, 2, 3, 4which have been operated. T hus, `for example, if all oi' the contactsin group I were operated simultaneously collecting switch A would rotateover its contacts and transmit' an impulse. to the motor magnet 'I ofadding switch.

A', for each of the operated contacts in group I, thus causing thisadding switch to step forward a corresponding number of steps. In theparticular arrangement shown each .of the switches A, A', B and B hasthree banks of 25 contacts. The normal and each successive fth contactof the bank A-I of the adding switch A' are connected together and incircuit with a relay 8 which is actuatedwhenever the wiper engages oneof these contacts. arranged to control an'additional relay 9 in a mannersimilar to that in which the contacts I, 2, 3, 4 control the associatedrelays I'2', 3'4'. Similarly the normal and every other contact of thebank B'-I of adding switch B' are connected together and in circuit witha relay I0, the contacts of which control an additional relay Il. Relays9 and I! are connected to a collecting switch C in the same manner inwhich the contacts I, 2, 3, 4 areassociated withA their respectivecollecting switches A, B and, accordingly upon each operation thereofcause the collecting switch C which is similar in construction toswitches A and B to operate over its entire bank of contacts thereby tosupply impulsesthrough a conductor I2 to the motor magnet I3 of an addiA representsa value offv 2, it will be apparentthat the impulsetransmitted by relay 9 through collecting switchC represents a value of10. In

.the same way since relay II is operated in response to every otheroperation of adding switch B', it will be apparent that impulsestransmitted by this relay through the collecting switch C representvalues of 10. 'Thus all of pulses transmitted through the collectingswitch C to the motor magnet I3 of adding switch C', represent equalvalues.

Switches C', D and E, each of which is similar in construction toswitches A, B and C except that C' and D have ve banks of contacts and'E has four banks of contacts, are connected in cascade relation in theorder mentioned; that is, these selector switches are so connected thatupona' predetermined number of operations of each ot these switches animpulse is transmitted The contacts of this relay are Y to the motormagnet of the next switch in the operation of that switch, and upon each10 vauch 'l5 predetermined operations of the switch D an impulse istransmitted to the motor magnet I 'l .causing a similar .operation ofswitch E. As

, be included in group 3, toa number determinedthe arrangement disclosedimpulses which have vof the system a many additional switches may ofcourse be included in the cascade connection as is desired. Thus it willbe apparent that the switches C',

`D and E constitute a totalizing device for the received impulses. Sinceeach actuation of motor magnet I3 Aof `adding switch C' represents y avalue oi' 10, each actuation of switch D will represent a value of 100and .each actuation of switch E will represent a value oi' 1000.Accordingly the total of values represented by operation of the keys I,2, 3, 4' may be indicated 'in any desired number vof'digits by means ofdials having cooperating pointers carried by the shafts of each oftheseswitches.

Since operationof contacts 5 represents a value of 10 the associatedrelay 5' is connected to the collecting switch C in the same manner inwhich the relays I', 2', 3', 4' are connected t0 their respectivecollecting switches. eration of contact 6 'represents a value of 50,this contact is arranged to control five relays of which, to simplifythe drawings, only two, 6' and 6" are shown. v.Each of'these relays isarranged to control the collecting switch C in the.

same manner in which the relays 5'; 9 and II control the collectingswitch C. Thus, upon each operation of contact 6, the collecting switchC willltransmitve impulses to the motor magnet I3 ofI adding switch C'.Since contacts 5 and 6 may be caused to transmit impulses of equal valuefrom their associated relays we have designated these contactsasincluded in a single group. .Similarly otherl contacts, the operation ofwhich represents different multiples of 10, may

by the magnitude of the multiples and the capacity of collecting switchC.

It will thus be apparent that the function oi the collecting switches Aand B is to collect the impulses rom the stations in groups land 2respectively. The function of adding switches A' and B' is to add theimpulses collected by the collecting switches A and B respectively andto transmit an impulse representing a predetermined multiple of thevalues represented by the impulses collected thereby each time thevalueof the total number of impulses received by the respective adding switchequals the predetermined multiple. Similarly the function of thecollecting switch C is to collect all of these impulses representingthis predetermined multiple and to supply them to the totalizin'gdevice' comprising the switches C', D and E. Since in a value less than1,0 are not added to the total until a suflicient number of suchimpulses have been collected so that the value represented thereby isequaly to 10,. these impulses which rep-v resent values less than 10 maybe called impulses of minor value1-and the impulses which represent thevalue lilimay be called impulses of V major value.

Having now generally indicated the character betterunderstanding thereofcmay Abe had by reference to its more detailed circuit arrangement andoperation.

Referring to Fig. 1 of the drawings, with all of the equipment in theposition illustrated, it

will be seen that y,relays I', 2', 3', 4', 5', 6', and 6" are allnormally'energized through a hold# ing circuit including their inner.right-hand contacts and the contacts of the respective conture anddeenergizingv itself, at the same time, Astepping the (wipers of each ofthe respective banks one step. Since'the outer righteliand contacts ofrelay I' Vare now separated the motor magnet vI9 will not immediately beenergized when the collecting switch A is in the first off normalposition. However, when the wiper oi the bank A-I engages its rst oinormal contact, relay I' is again energized through an obvious 'circuitthereby closing its right-hand contacts and energizing the motor magnet.I9 which in turnsteps the collecting switch to its second off normalcontact. The second off normal contact of bank A--3 is connected throughthe outer right-hand contacts of relay 22.- which are now closed to thenegative bus. Accordingly motor` magnet I9 is again energized and stepsthe wiper of the'bank A-'3 to the next 'contact which, to illustrate theoperation Nef. the equipment, is shown permanently connected tothenegative bus I8. Thus the motor magnet I9 will actuate.

collecting switch A over its entire bank of contacts and return to itsinitial position where it will be deenergized by the outer left-handcontacts of relay I'.

When the wiper of the bank A--2 engages its rst off normal contact acircuit is momentarily Acompleted which extends from the negative bus I8through the inner left-hand contacts of relay I' which are closed atthis instant, erst cfr normal contact of bank A-2, contacts of relay56,-motor magnet 'I of adding switch A' backjto the positive bus 20.lThus motor magnet '1 re-A ceives one impulse.

The manner in which impulses are. transmitted to the motor magnet 51 ofadding switch QB in response to operation of' the contacts in group 2is'the same as that which has been described in connection. with theoperation of switches A' and A, and therefore will not be 4furtherrelated.

Since selector switches of the type employed in the system areordinarily constructed with 25 contacts in each bank, it will now beapparent that there may be as manyas 24 stations included in eithergroup 1 or group 2. It will be apparent that ifall of the switches inany group are operated simultaneously, the corresponding `collectingdevice, or v,selector switch A, B, will rotate through a complete cycletransmitting impulses in succession over the single conductor whichconnects the wiper of bank A-2 to the motor magnet 1, and at the s ametime restorirfg the corresponding' relays to the normal position wherethey are in readiness'fo'r the next operation.. Similarly the same willoccur independently of theorder in which the contacts of any group areoperated. All ofthe relays in any group are interlocked by-'means oftheir outer right-hand contacts to prevent any loss offimpulses. Thus,for example, assuming that collecting switch A is on its Vsecondoff-normal contact due to operation of relay 2', when relay- I' isoperated; it will rst energize'relay 2' and relay 9.

transmit the corresponding impulse to the motor magnet 1 after which itwill return to the normal position. Since the circuit of the normalcontact is completed by relay I' it will again rotate over its bank ofcontacts and restore relay I to the normal position` and send itsimpulse to the motor magnet 'I.

The normal contact and each successive fifth contact of the bank A'-I ofadding switch A' are connected together and in circuit with relay 8across the negative and positive busses 'I8 and 20. The armature of thisrelay 8, in either position thereof, engages one of two contacts whichare connected together and which are included 'in the holding circuit ofrelay 9. Thus upon the first actuation of adding switch A' relay 8 isdeenergized and its armature momentarily interrupts the above describedcircuit -for However, simultaneously therewithv a circuit is completedfor relay 9 which extends from the positive bus 20 through the Wiper and`rst off-normal contact of the bank A-3 of ing the collecting switch Cto complete its rota.

tron. 'Ihus it will be seen that one impulse repvhand contacts thereofto the negative bus.

Thus no operation of relay 9 occurs. This circuit is also `completedthrough the second, third and fourth off normal contacts of the bankA'-3. Whenthe adding switch A engages its fth off-normal contact,however relay 8 is again energized and momentarily interrupts theholding circuit of relay 9, and relay 9 is then deenergize for thereason that theabove described ci cuit through the wiper and contacts ofbank A-3 is not completed when the wiper is in this position.Accordingly relay 9 will close its left-hand contacts and interrupt itsrighthand contacts. which extends from the negative bus through theouter left-.hand contacts of relay 9, conductor 2|, normal contact andwiper ofthe bank v C3 of collecting switch C and motormagnet 22 ofcollecting switch 'C to the positive bust When: the wiper of the bankC-2 engages its contact which is connected to conductor 23 an impulsewill be transmitted through the inner left-hand contacts of relay 9,conductor 23,

.wiper ofthe bank C-2, conductor I2, contacts 'I2' on relay 56, andmotor magnet I3 of adding switch C' to the positive bus.

Simultaneously therewith a lcircuit is com-- pleted through conductor 24and wiper of the bank C-I of the collecting switch C, which in turnrestores relay 9 to its initial position thereby applyingneg'ativepotential throughits outer right-hand contact and conductor 25to the corresponding 'contact of the bank C-3 andcausresenting a valueofl l is supplied'to the motor magnet I3. When the adding switch A'steps an additional step relay 8 is again deenergized and will remain'deenergized for four successive steps of the 4adding switch A' but relay9 will not be operated for the reason',that its circuit is completedthrough the succeedingfour contacts, of

Since Vrelays I0 and Il, are Wired to the switches B' and C in the samemanner in which the relays 8 ancl 9 are wired to theswitch A' and C..their operation will not beA further described.

However, since each operation of the adding switch B' represents a valueoi 5, every second on? normal contact on Abank ,B"-I is connected withrelay III rather'than every fifthoi lnormal contact as inthe caseof thebank .A2-FI. II'hus A circuit will then be completedcomplete revolution.

tion of switch B', and therefore serves to supply impulses representinga value of through the bank C-2 and conductor I2 to the motor magnet I3of adding switch C'. Since relays 5', 6' and 6" are wired to thecollecting switch C in the same manner as has been described inconnection with the other relays I', 2', 3', 4', 9 and II no additionaldescription thereof is necessary, it being pointed out that there are verelays 6', 6", etc. which are controlled by the contacts 6 such thatupon each operation of contact 8 all of these relays are deenergizedcausing the operation of collecting switch C which in turn rotatesrestoring these relays to their initial position, and transmitting animpulse having a value of 10 from each of these relays to the motormagnet I3 of adding switch C.

In connection with the adding switch C it is to be noted that thisswitch has ve banks of contacts instead of three as is the case withadding switches A and B. The reason for this is that it is desired totransmit an impulse from this switch C' to the next switch D in thecascade arrangement in response to each 10 actuatlons thereof. As hasbeen stated each bank includes 25 contacts. Thus, if the switch C'- wereconnected in the manner in which switches A' and B' are connected on,receipt of twenty-live impulses the wipers of the switch C would beoperated through one-half of a revolution. yBy arranging the wipers ofbanks C'-I and C'-2, and C' 4 and C'-5 to extend in diametricallyopposite directions and by connecting these wipers together these banksmay be made to perform the' function of a single circular bank having 50contacts. Thus upon receiptof impulses the wlpers are actuated through acomplete revolution -and returnedto the initial position. 'I'he normalcontact on C'-I and each successive tenth contact on 'banks C'-I andC'-2 may thenbe con- Vnected together and in circuit with-relay I4 forD, and thence'through the wiper and motor magnet IB- of the switch =D tothe positive bus. The intermediate lcontactson bank D--S being con`nected directly to the negative bus, switch D will then be actuated toits( fifth off-normal position where it will again vawait deenergizationof relay I5, this relay having been energized through the intermediatecontacts on bank D-4 and having completed vitsholding circuit throughthe contacts of relay I4. Upon the next step of adding switch C' relayI4 will be deenergized but relay I5 will not operate for the reason thatits holding circuit is'maintained through bank C'-3. Thus relay t5responds onlywhen relay I 4 becomes energized. After another ten stepsof adding switch C relay vI5 is again deenergized and switch D isstepped through another five operations.

Since the motor magnet I6 advances the wipers of the switch D five stepsin response to each received impulse, it will beseen that in response to10 received impulses the wipers will rotate one Accordingly the wiper ofbank D-I of switch D is arranged oncein each revolution to supply animpulse to the next serelay Il is Qpez'ajged once fgr every otheropera-IECOI SW'Ch E in the Cascade arrangement.

` end of totalization, relays 29. and 56 are provided,

this purpose the twenty-fourth off-normal contact of bank D|, upontwhichthe wiper rests only momentarily, is. connected to the rst and eachsucceeding fth contact of bank E-l. This selector switch likewiseadvances five steps for' each received impulse, and its" bank E-l isarranged once in each revolution to supply an impulse to the motormagnet of the next selector tch not shown.

Indicating dials 26, 21 having cooperating pointers mounted upon theshafts of. the selector switches E and D may 'be provided, each dialcorresponding to one digit of the total which is to be indicated, thatis, the -dial 21 may represent represented by operation of contacts I,2, 3, 4,

5. 6, etc. will be indicated inV even hundreds and thousandsrespectively by means of the dials 21, 26 and their cooperatingpointers.

In order to restoreswitches A', B', C', D and E to their normalpositions, as for example, at the the relay 53 being normally energizedand relay 20 normallyl deenergized'. These relays are controlled bymeans of a key 30, which is normally contacts of the bank A'2 of addingswitch A" with the exception of the normal contact are connectedtogether and through one pair or contacts on -relay 23`to the negativeside of the batl tery. The wiper of this bank of contacts-is con-vnected tothe stationary contact which cooperates with the amature of themotor magnet 1, and

- thence through the motor magnet to the positive side of the battery.Thus it will be seen that when the'contacts on relay 23 are' closed abuzzer circuit including this bank'- of contacts and the motor magnet ofrelay ,1' is completed, by means same manner. Adding switch C' issimilarly pro. 'vided with banks of contacts C'I and C'-5. All of the@tacts 'oi these banksV with the exception of the normal contact of bankC'-5 are connected together and operate in the same manner to restorethe switch to its normal position.

As has already been stated the wipers on these banks extend in oppositedirections. vFor the same are provided upon vthe switches D and Earespectively. At the same time the impulse transmit- A 26, havingpointers for indicating m even mow sandsthe total indicated by each oi.'the different ting circuits extending through the motor magnets of thediiierent switches, except those oi'- the collecting devices A, B and C,are interrupted by f relay I6 permitting these motor magnets tol beenergized only through. the associated resetting banks whichare providedfor the purpose.

Let us assume that in. a particolar installation' there are employed aplurality of systems such as l that shown in Fig. 1 each'of whichtotalizes the values represented by the sales oi' tickets, for example,with respect to a particular feature of an` exhibition or. the totalpower indicated by the diiierent meters of a power distribution system,4

motor magnet 36 of adding switch F' which is similar. to switch C'. Thiscollecting device F is controlled by means oi'- relays 33, 3l each ofwhich is controlled from one of the systems corresponding to the systemshown in Fig. 1. For example, relay 33 is connected through conductor35to the contacts on relay I4 such that this relay is de'- energizedsimultaneously with relay l5, and relay 34 is connected throughconductor 34' .to a similar point on another system.

to rotate through a complete revolution and to transmit an impulsethrough the inner left-hand contacts of relay 33, rst oil-normal contactand wiper. ofthe bank F--2, conductor 3|, contacts 3|' on relay 56,conductor'32 and motor magnet 36 of the adding switch F'.V 'I'husim'pulses received by the motor magnet 38 of the adding switch F'represent values of 100. Switch F' is connected in the same manner inwhich switch C is connected and controls 'relays Il' and I5'- which inturn supply impulses representing values of 1000. to the switch G in thesame mannerin which relays I4 and l5 supply impulses repre' sentingvalues of -100 to switch D. Switch VG which is similar to switch D isconnected in the same manner in which switch D is connected;`

'that is, the wiper of the bank G-l is connected A corresponding relaywill be providedfor each system. Deen- -ergization of relay 33 causescollecting device F through conductor 31 andcontacts 31 on'relay '56 tothe positive battery; the contacts of banks spondingcontacts on G-Iareconnected directly to negative battery, thus it will be seen that theimpulses which are supplied to theswitch G represent values of 1000, andthat in responseV to each of these impulses this switch is actuated'through ve steps and in response to10 such -impulses the switchcompletes a revolution and supplies an impulse through the wiper of bankG-I to the next switch H in the cascade connection.

'I'hese switches, and as many others as may be desired,` are similarlyprovided with dials 21' and systems.

' In case it is desired to produce the indication of total indicated bythe system in Fig. 1 at a plu'- rality of different points, thismay bevaccomplished by providing relay I5 with one or4 more additionalleft-hand contacts 4I and causing each -of these contacts to controladditionalcascade, v vconnected switches corresponding to switches C',

The indication may be provided at these diierent points by means ofIamps,'as shown in Fig. 3.

In connection with switches D, E anidG it will be` -impulse. It will beseen that in this way sumcient mechanical displacement is provided topermit easy reading of the dials. Where the total is to be indicatedelectrically as by means of lamps, for example, this is not necessary,and the nrst indicating selector switch may-.be wired as shown at D' inFig. 3 and controlled. by relay I5 of Fig. 1. That is the motor magnet42 is'connected in a circuit which extends from positive battery throughthe motor magnet 42, normally closed contacts on relay 56 (which arerepresented at 56 in Fig. 3), contacts on relay I5 (which are'represented at 4I in Figs. 1 and 3) .to the negative side ofthebattery. Thus upon each deenergization of relay I5 the motor magnet 42of the switch D' is energized through this circuit. When relay I5 isagain energized'by bank D-4 of switch D, motor magnet 42 of switch D' isdeenerglzed and switch D' is advanced one contact position. Thus switchD' is advanced one step for each received Since the bank D'-3 has 25contacts' impulse. ve of these contacts are connected directly to thenegative bus. The wiper of this bank is connected to the stationarycontact cooperating with the armature of the motor magnet so that theswitch is actuated over these ve contacts by buzzer action and isreturned to the initial position in response to twenty receivedimpulses.. Preferably these contacts are so chosen, as indi- 4cated inFig. 3, as to separate the remaining contacts into two groups of tencntacts each. 'I'hese contacts are connected through'v contactsonresetting relay 29 (which are indicated at 29 in Fig. 3) to thenegative battery. .Thus this bank is utilized as the resetting bank forthe switch D'.

The bank D-2 controls the indicating lamps corresponding to the hundredsdigits of the total.

Thus when the switch is in its initial position the lamp correspondingto zero is'lighted. vWhen fit is in position I the lamp corresponding to10 is lighted, and so on, for the position of the other integers. BankD\I serves to supply an impulse to the next selector switch in thecascade connection in responseto each 10 received im pulses, whichswitch, in turn, controls the lamps means whereby theaccurate total maybe indicated rather than the total as represented by even hundreds orthousands.

AI, B'-I vand C-I, and C"-2 in the manner shown in Fig. 4. The wiper ofeach of thse banks is connected to negative potential and each of thesecontacts is connected through a lamp on the indicating panel 54 topositive potential, the lamps serving to indicate the number of impulseswhich has caused the wiper to be actuated This may be ef- `fected bywiring the unused contacts on banks the lamps indicating values 10, 20,30-90, colitacts on bank A'-I control lamps indicating values of 2, 4,6, and 8 and alternate contacts'on the bank B' being connected to asingle lamp indicating the value 5. Thus the total value indicated bythese lamps corresponds to the value represented by impulses which arestored in the equipment at any particular. time, and which is notincluded ih the total as indicated by the selectors D and E. 'Ihe sameresult of course may be' had by means of dials mounted upon theseswitches. Similarly the accurate grand total may also be had by alsowiring the banks F'I F-2 to indicating lamps in the manner shown inconnection with banks C'I 'and C-2.

For out of door purposes or for purposes of large gathering places. itmay be desirable to indicate each of the digits by means of. a grou'p 0flamps', as is lshown in Fig. 6, for example,

Where each of the numbers represented in rows I, 2, 3 to II) correspondto the total indicated by a system such asthat shown in Fig. l, and thetotal which is indicated at the bottom of the tlgure corresponds to thegrand total which is indicated by the equipment shown in Fig. 2. It willbe seen that' each digit of each of these quantities is indicated by aplurality of lamps; For the purpose `of controlling the lamps comprisingany particular digit the means represented in Fig. 5 may be employed.This means comprises a selector switch I having banks I-I, 1 2, I-3 andI-4 plus one additional bank not shown, which may be wired in the mannerindicated in connection with bank D3 of Fig. 3, for example, such thatupon each impulse oi the first nine impulses Iii' received, the switchadvances one step. Upon receipt of the tenth impulse the switch advancesover two contacts and stops upon the next. contact which corresponds tothe zero position. Upon receiving each of the next nine impulses itadvances one step and upon receiving the tenth impulse advances threesteps to the position shown in the drawings.

Associated with this switch are a plurality of relays 44, 45, 46, 41,48,49, 5U and 5I. I'he relay .44 is-controlled by the wiper of the bankI-4 and the remaining relays are controlled by the wiper of the bank I-Sthrough obvious circuits which may be readilyy traced from the drawings.When these relays areenergized their armatures are actuated to the left,and whe hey are deenergized their armatures are actua The position ofthe selector switch in which the respective relays are energized isindicated by the following table Integer indicated and switch positionRelay Energized 0 44 5l 1 None 2 44 3 44 45 4 46 5 44 47 6 44 48 7 44 49R 44 9 v 44 50 The lamps L comprising each digit are arranged in vecoliunns of six each and are controlled through relays 44 to 5I andthebanks I-'I and I-2 of the selector switch. One terminal of all to theright.`

Bearing in mind which of the relays are energized and the position ofthe selectorswitch, the circuit of each of the lamps which are lightedwhen any particular integer is to be" indicated may be very readilytraced. Thus, for example, if zero is to be indicated the switch will bein the zero position which is that shown inv theA drawings and relays 44and 5l will be energized. The lamps which should be lighted may bedetermined from Fig. 6. A circuit is completed for lamps lig-1, L-I3 andL-I2 through the left-hand contact and armature of relay 44. Lamp L-l 9is lighted in all digits andtherefore is permanently connected acrossthe circuit 52. L-26 islighted through the right-hand Yarmatures ofeachof relays 48, v41 and 45 in their right-hand position, and armatureof relay 4,4 in its lefthand position.

When the switch is advanced to its 4ilrst off normal position relays 44and 5| are -deenergized and all ofthe lamps, with the exceptiomof lampL--l9 which is permanently lighted, andi- 24, are extinguished. In thisposition none of the relays is energized., Lamp L-Zli is lighted throughthe wiper of the bank I-|.'
